No child is born without love for their parents. As I said, mental conditions are to blame for most criminals. They may be fully aware of what they're doing, but if they can justify taking someones life... I do consider them mentally ill and not able to differentiate between right and wrong, as held by normal human standards. Like the thug rapists you mentioned.... in his mind he thought those girls deserved that... Why did he think they deserved that? He never developed the ability to choose right from wrong. Should we kill him? No... but we should prevent him from hurting innocent people in society by jailing him... let him read all he wants from the prison library... maybe he'll learn something.
